Taming rate: select rarity, taming level and +card to show your chance of success.
May not be entirely accurate for soulpets (lacking sufficient data there) and I am fairly sure creature taming scrolls always count as 20+0 and ignore your card (but not entirely sure, I’m afraid).
Source of the image: Arab Servers, tested by one of their GMs WAY back. According to my long-term-tame-stats, it seems to be a fairly accurate aproximation of what we really have.
Derived from that, the following formula for taming rates can be used:
Unique: 1% + 0.07% * skill + 0.04% * card
Special: 1.51% + 0.104% * skill + 0.06%*card
Rare: 2% + 0.14% * skill + 0.08% * card
Special Basic: 7% + 0.49% * skill + 0.28% * card
Basic: 25% + 1.75% * skill + 1% * card
NPC Basic: fuq you.
Kinda lazy right now, but I may add a calculator for any given rarity, card and skill level at some point… for all those that consider maths something impossibly hard ;-)
Also this means my level 14+5 taming gives me an impressive 2.18% taming chance on death tyrants, wds or arena pet.
Even assuming the best believable interpretation of the summoning scrolls adding +50%, that would most likely be “half again”, so 3.27%… yay, totally likely I’ll go 2/5 on drillbots if I try, right?
